In winding machines in which the packages being wound have their axeshorizontal and are rotated by having whirls on their cores resting onsubj acent rotary driving wheels it is known to support a roller undereach package so that when the latter attains a predetermined diameter itwill peripherally engage the roller and thereby have its whirl raisedout of contact with the driving wheel so that the driving will bestopped. This invention has for its object to provide for support of theroller by means which will not only be adjustable substantiallyhorizontally and verticallyhorizontally, so that the roller may bebrought into some desired relation to the vertical plane of the axis ofthe package, and vertically, so as to determine the diameter of thepackagebut which may be manufactured at the minimum of expense andreadily applied to any winding machine of standard type.

In the drawings, Fig. 1 is a side elevation, partly in section on line1-1, Fig.2, of so much of a winding machine as embodies the invention inone form thereof;

Fig. 2 is a front elevation;

Fig. 3 is a plan of said form;

Fig. 4 is a side elevation and plan, partly broken away, of a detail;

Fig. 5 shows, partly in plan and partly in section, the bearing supportfor the roller,

Fig. 6 is a side elevation of another form, with a part of the machineframe shown in section;

Fig. 7 is a front elevation of this form; and

Fig. 8 is a plan thereof.

Let 1 designate the usual pair of horizontal bars forming a part of awinding machine 4 frame of standard type; 2 the driving wheel carried byand rotating with a horizontal shaft .3; and 4 a pair of brackets formedwith guide-Ways 5 for the package trunnions, the core of which packagemay as usual consist of a spindle 6 (whose ends form said trunnions)having a driving whirl 7, which receives the driving contact of thewheel 2, and a spool 8 removably fitted on the spindle and on which thewinding of the thread or yarn is directly effected.

According to this invention the roller -9 with which the periphery ofthe package contacts whenthe predetermined diameter of the latter hasbeen attained is ournaled in a bracket which is adjustable substantiallyhorizontally and vertically and is angular in plan and has one armsupporting the roller and the other affixed to the frame, its angularform as specified making it very inexpensive to manufacture and readilyadapted to fit any standard frame and be capable of the adjustmentsmentioned.

In the formshown (preferably square) at the other end. A bearing supportfor the roller 9 is formed by a headed pin 13 whose reduced stem 13apenetrates the slot 11 and also a washer '14 and a nut 15, the formerbeing adapted to abut a' p in Figs. 1 to' 4 this bracket is constructedas follows: An elongated strip 10 has a slot 11 extending longitudinallyfrom one end thereof and a hole 12 and the other wing 16c thereof formedwith a slot 160? which extends parallel with the line of bend of theplate. This slot receives a bolt 17 (Figs. 1, 3 and 4) which has asquare portion 17 a fitting the hole 12 in the strip 10 and also a nut18 and a washer or washers 19 to coact therewith to clamp strip 10 tothe wing 160 of plate 16, with the bolt penetrating slot 1603. In thenormal position the strip 10 extends substantially perpendicular withreference to slot 16d, as shown in Fig. 1. Wing 16a of the plate bears'againstboth bars .1 and is rigidly held thereagainst by ascrew 20 whichpenetrates hole 16?) and is screwed into a plate 21 between which andwing 16a the bars are clamped by the screw. The construction is suchthat the bracket is adjustable both horizontally and vertically so as tochange the position of the roller in either of these directionstransverse of the axis of the packagehorizontally, by shifting that partthereof which is constituted by the bearing support for the rollerlengthwise of that part thereof formed by strip 10, and vertically, byshifting the strip lengthwise of the bend of plate 16. Both parts 10 and16 may be of sheet metal.

Referring, now, to Figs. 6, 7 and 8: Here the bracket is in one piece.It consists of a T-shaped piece of sheet metal having the head 22 of theT, forming one arm of the bracket, bent into a plane perpendicular tothe stem 23 thereof. The stem 23 has extending from its free end alongitudinal slot 24 in which a suitable bearing support 25 may bearranged. The arm 22 of the bracket has a slot 26 extending parallelwith the bend in the piece and a washer 27 abutting it which arepenetrated by a screw 28 which extends between the frame bars 1 and isscrewed into a plate 29 which coacts with the washer to clamp said armto the bars 1 on said screw being screwed up tight. Here again theconstruction is such that the bracket is adjustable both horizontallyand vertically to change the position of the roller in either of thesedirections.

In the first form on the wing 160 of the plate, and in the second formon the arm 22 of the bracket, I preferably provide a scale 30, which maybe marked with suitable indices, whereby the elevation of the roller andhence the diameter which the package will attain before the winding isstopped may be determined.

Fragments of the windings wind around the bearing device, accumulatingto such a degree as in time to stop rotation of the roller if they arenot removed. This is possible by removal (on loosening nut 15) of thebearing device and roller as a unit, such removal being in turn possibleby slot 11 being openended.

Having thus fully described my invention, what I claim is:

In a winding machine, an attachment for stopping rotation of a spoolresting, with its axis horizontal, on a rotary driving member,

- including, in combination, a plate bent to substantially a right angleand having the wings formed both sides of its bend arranged in uprightplanes, one wing forming the supporting portion of the plate and theother having an upright slot, a flat strip bearing against the latterwing, means, penetrating the slot and strip, to secure the latterrigidly to the second wing, a bearing device secured to the second wing,and a spool-engaging roller journaled on the bearing device.

In testimony whereof I affix my signature.
